The 4.6 earthquake registered in the capital this Tuesday was due to a “secondary fault” to the “Quito fault”, says Dr. Marco Ruiz, seismologist and researcher at the Geophysical Institute.
Today’s earthquake did not occur exactly in the main segment of the Quito Fault, but it is associated. “It has the same orientation, but it is slightly displaced towards the east. It has the same mechanism, direction on the surface, the same orientation of the plane, it responds to the same sources as the Quito Falla, but it is not the main segment of it ”, he emphasized.
According to social networks, the earthquake seems to have been felt more strongly in the north of the city and has caused the landslide and rocks next to the Guayasamín tunnel, one of the main accesses to Quito from the valleys surrounding the capital. that caused damage to a vehicle and forced to close the subway.
